GEORGE G. KNIFFIN, OF BROOKLYN, ASSIGNOR TO HENRY E. JANES AND HERBERTJANES, OF NEIV YORK, N. Y.

STOVE OR RANGE.

SPECIFECATION forming part of Letters Patent No. 398,515, dated February26, 1889.

Application filed October 10, 1888- $erial No. 287,758. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE G. 'KNIEFIN, of Brooklyn, in the county ofKings and State of New York, have invented new and useful Improvementsin Stoves or Ranges, of which the following is a full, clear, and exactdescription.

My invention relates to an improven'lent in stoves or ranges, and hasfor its object to provide the said ranges or stoves with acounterbalance drop-door specially adapted for use at the oven; and thefurther object of the invention is to attach the doors in a simple anddurable manner, and provide a means whereby the said doors will be easyof access in the event repairs are needed.

The invention consists in the construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of a range having double ovens. Fig. 2 isa central transverse section on line 00 acof Fig. 1, illustrating theinvention, the inner partition-wall being partly broken away. Fig. 3isan essentially longitudinal section, and Fig. 4 is a transversesection on line y y of Fig. 1.

In carry out the invention, A 1.-e n'esents a range containing a centralfire-pot, A, and an oven, B, at each side of the latter, which ovens atthe bottom are separated from the bottom of the range by the usualhorizontal partitions, Z), the inner end of the said partitions beingconnected with the inner side of the ovens, as best shown in Fig. 3.Perpendicular partitions C are cast integral with the bottom of therange or attached thereto, which partitions constitute the side walls ofthe ashpit C.

Upon the upper edge of the 'said perpendicular partitions a secondperpendicular partition D is detaehably fitted, and the said latterpartition D is carried upward parallel with the inner side of the ovensto the top of the same, at which point an integral pro3ection, (1, isformed extending at a right angle outward to a detachable connectionwith the oven, as best illustrated in Fig.

A space, E, is made to intervene the detachable partition D and theinner oven-side, and a series of lugs, (l, are preferably projected fromthe oven-side to support and brace the partition D, the lugs beingarranged upon an arc of a circle, as best shown in Fig. 2.

The oven-doors H, which are adapted to swing downward, are'provided uponthe side contiguous to the fire, at the bottom, with an attached orintegral counterpoise-weight, I-I, extending through an aperture, h, inthe front of the stove into the space E. The weight H is made to justbalance the door, and prefer- 6 ably provided with a cylindrical outeredge, h whereby as the door is lowered and the weight ascends thecylindrical surface of the latter will travel in contact with and beguided by the lugs (Z.

The upper face, it, of the weight is usually made straight and providedwith a notch, 70, and a post, if, purposed to enter the notch is whenthe weight is fully elevated, is secured to the inner face of therange-front at a suitable point.

In operation as the weight effectually balances the door the latter maybe raised or lowered and retained at any angle intervening a horizontaland a perpendicular position. Again by the use of a counterpoise-weightthe door if opened suddenly and dropped will not break at the hinge, asthe force of the fall is broken by the weight. hen the door is closed,the weight is below the bottom 8 5 line of the oven, as shown in Fig. 3,with the top horizontal, as illustrated in Fig. 2. When the oven-door isfully opened, the straight sides of the weight are brought in closecontact with the inner face of the front of the range, and are held insuch position by the post entering the slot in the weight.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- 9 5 1. The combination, with the stove orrange having a vertical space at the side of the oven, of thevertically-swinging oven-door having a weight the upper face of which isat right angles to the inner face of the door to rest against the innerside of the front when the door is swung down to a horizontal position,substantially as set forth.

2. The combination, with the range having the two partitions C C, the.side ovens, and the detachable partitions D D, resting on the upperedges of partitions C C, parallel with the ovens and having horizontalprojections (I along their upper edges engaging the upper ends of theovens, of the downwardly-swinging doors hinged at their lower ends tothe range-front and having integral weights working in the spacesbetween the ovens and partitions D, the upper faces of the weights beingat right angles to the inner faces of the doors, substantially as setforth.

The combination, with the oven of a stove or range, a spaced detachablepartition parallel with one side of the oven, and horizontal guide-lugsattached to said oven, arranged upon the are of a circle, of a dropdoor,and a counterpoise-we'ight secured to the door capable of movementbetween the oven and partition, provided with a cylindrical outer edgeand a straight upper surface, substantially as shown and described.
